Out of the last 20 questions (most asked more than a day ago), 15 do not have an answer or no upvoted answer (this is the case for the 14 latest). On a slightly longer prespective it also feels like our answer% has dropped a bit (do not have stats though - are there any for moderators on e.g. answer% / month).
Do we have a problem of handling the influx of new questions? I would imagine that it is problematic if people do not get relatively quick answers, especially to basic questions (people asking harder, research-based questions can probably wait a bit longer). If visitors get the impression that questions are not answered, they might get the impression of an inactive community and may not come back.
Maybe this is just a temporary slump, but I was surprised to see this many unanswered questions.
